hello,
i ve got a problem with the querybyrect method with mapserv4.0

for ($i=3D0;$i<$nblayer;$i++)
{
$oLayer =3D $oMap->getLayer( $i );
          if (@$oLayer->queryByRect($oRect) =3D=3D MS_SUCCESS)
    {
$oLayer->open();

     $szResults=3D$oLayer->getNumResults();
     if ( $szResults > 0)  //i find 14 shapes
     {
           for ($j=3D0;$j<$szResults;$j++)
          {
           $oResults=3D$oLayer->getResult($j);
           =
$oShape=3D$oLayer->getShape($oResults->tileindex,$oResults->shapeindex);
           $oShape->free();
          }
     }// if ( $szResults >0
     $oLayer->close();
    } //if (@$oLayer->quer=20
}// for
i find 14 shapes but the getshape method crash
PHP Fatal error:  [MapServer Error]: msOGRLayerNextShape(): Assertion =
failed: OGR layer not opened!!!
Any idea?
